rapid prototyping? what material should i use for sand casting?

what is the best material out there to rapid prototype a part from when using it for a sand cast mold?

Maybe you should consider a rapid prototyping service.

You probably want to choose a system that produces a good prototype that has dimensional stability over time, so I’d avoid sterolithography and choose one that uses a plastic material. I’ve linked info on the various kinds of rapid prototyping available.

    zinc – easy to melt and shape, and cheap. Just be careful of zinc fumes, work in a ventilated area and use a respirator.
